Mark One is a sci-fi themed twin-stick shooter featuring lots of shooting & robots. Humans have evolved to a level that allows them to build robots for performing tedious tasks. When Artificial Intelligent peaked, some robots went rogue and retaliated against humans, completely ignoring the failsafe switch which was built into their systems. This is where you step in. You are a highly trained AI agent tasked with the responsibility of disposing bots which have gone rogue. Main features: 6 levels with varying objectives 3 boss fights A range of weapons to use during the fights Several different robots to fight against Lots of explosions A devastating skill named sonic punch The gameplay has been designed in a way that encourages you to face multiple enemies at once.
